Filed: 1980-10-14
Abstract: PURPOSE:To assuredly prevent forgetting the confirmation during the switching, by detecting the switching of a changeover switch between the on-line and off-line modes and the automatically delivering the data of a transaction counter. CONSTITUTION:When a mode changeover switch M is switched, a switch detection part DT detects the rise or fall to start the readout to the readout part RD. Accordingly the part RD reads out the respective transaction counters by one on each start to give them to a print control part PC. At the part PC, the given type-based code and the total data are supplied to a printer PR to be printed. This prcedure is carried out in the same way although the on-line mode is switched to the off-line mode and vice versa. When the signal ''1'' that designates the off-line mode is supplied to a transmission control part TC, the transmitting function of the part TC is turned ineffective. Thus the transmission of data becomes impossible.

Title: Solar heat collector
Inventor: MAKI MASAO
IPC: F24J2/48
Filed: 1982-08-18
Abstract: PURPOSE:To realize highly reliable selective absorption on a high-density polyethylene base material, the bonding onto which is normally difficult, by a structure wherein metallic powder in a first coating layer suppresses the infrared radiation from high-density polyethylene used as the base material and yet a second coating layer having a selective absorptivity of the sunlight is formed onto the first coating layer. CONSTITUTION:The first coating layer II mainly consists of thermoplastic acrylic resin, alkyd resin, chlorinated polyethylene, or epoxy resin 2 and metallic powder 3. The second coating layer III has excellent absorptivity in the visible light range of the sun and sufficient transparency in its infrared range. Consequently, the sunlight A is absorbed by the second coating layer III and at the same time converted to heat in order to heat-transfer to a heat transfer medium side (b). On the other hand, the radiation loss from the surface is small by being governed by the metallic powder 3 in the first coating layer II, because the second layer III is sufficiently transparent with respect to infrared rays, resulting in realizing sufficient selective absorption. In addition, because of the base material being of chlorinated polyethylene, no difficulty is aroused in bonding work.
